July 1 marked the anniversary of the first international phone call, which was placed in 1881!

The first call was between St. Stephen (Canada) and Calais (United States). Western Union had installed the first telephone exchange in St. Stephen two years before using Edison’s systems, and a few days later Dominion Telegraph installed a competing, but incompatible exchange.

Both merged into Bell Telephone several years later, and the first international phone lines were set up.
